Yes, I have. I was unable to play for a couple of weeks due to the PSN outage... I have accumulated about 245 hours of time into the online game and am about to reach 12th prestige. The online portion of the game is fun, and addicting like the previous CoD games. If you are considering just joining into the multiplayer fray now I would recommend that you do not pour too much into it, as Modern Warfare 3 comes out this November and if past history is any indicator the community for Black Ops will die off soon after.
I am going to make a pretty substantial list for different consoles of games I know many people never played and did miss out on a great experience.
Shadowrun - Sega Genesis and Super NES (they were 2 seperate games with unique story lines, no port here)
Ogre Battle - SNES
Princess Tomato in the Salad Kingdom - NES
The Horde - Sega Saturn
3rd World War - Sega CD
Armada - Sega Dreamcast
Tecmo's Deception - PS1
Worms - PS1
Conkers Bad Fur Day - N64
Aerobiz - Sega or SNES
Liberty or Death - Sega or SNES
Naval Ops Warship Gunner - PS2
Summoner - PS2
No More Heros - Wii
Valkyria Chronicles - PS3
Dragon Warrior Monsters - Gameboy
Who Framed Roger Rabbit - NES
I could think of some more, but now I have the urge to bust out many of these games and play them again and I have too many current games I haven't finished yet.... Aaaaaaaahhhhhhhhhhh!
I would argue that arcade failure in the United States can be attributed to social change. Where the daily interactions of a populace in Japan have remained relatively unchanged in the last 15 years, the social interctions of the American people has changed dramaticly. The same argument could be made for Drive-In theatres and their decline as well. I will however make that arguement that just because this is the way it is today, does not mean it will always be that way. We very well could see a resurgence of the social type gaming atmosphere that is represented in arcades at some point....
I agree with wghj55, the commercial is too short to take a whole lot out of it. I am excited by the prospects of the directions they can take. I am most looking forward to some more great multiplayer. If they do introduce vehicles, especially as they did in World at War, I may be concerned, as there can be balance issues.... Here is looking forward to the whole trailer.
I play in the occasional Texas Hold'Em tournament. I am leery to play any video games at the professional level as that would entail training, which is akin to work, and once it is work, it usually is the last thing you want to do for fun. So basically I am afraid of taking my favorite past time of gaming and turning it into a job, and then not loving the way I do now.
Averaged out including new hardware purchases, for both the PC and consoles, probably 25k or so........ I guess it really adds up, but in the grand scheme of things you only live once, and if your not having fun as often as you can then what are you doing with your life?
